Disclaimer: This report is a part of a project work for one of the largest steel and iron manufacturer in India and has been written to meet the academic requirement of a dissertation work. Any part of this work or data cannot be used or reproduced in any way.
The energy footprint of industries like steel and iron, cement, fertilizers is almost half of the total primary energy in India. This work is an application based project for TATA Steel Limited (Company). The Company has assigned The Energy and Resources Institute to develop Renewable Energy (RE) road map for them to meet the twin objectives of sustainable business practices through RE integration to meet Renewable Purchase Obligations (RPO) and reduction in Green House Gas (GHG) emissions throughout their supply chain. However, as a part of my dissertation I have focussed on only solar PV applications, which can be intervened to meet the primary objectives. A comparative analysis is also done for a single ground mounted solar PV project through HelioScope and PVsyst.
The study area of this work covers only Jamshedpur and Kalinganar, where the company has steel production plant and township areas. An extensive location wise multiple visits were made to identify the potential sites; several parameters like roof area, structure, shadow objects, parapet walls were considered and around 70 locations were identified suitable for solar PV projects. All the system designing and simulations were done using a web based tool HelioScope. It was found that TSL.
Through this work, 121 MW of solar PV applications are proposed in Jamshedpur and Kalinganagar including floating solar, rooftop solar and ground mounted solar applications. Detailed techno-commercial feasibility analysis was done for each individual location and it was found that the company will require around INR 531 crores capital cost to put these projects in place and will generate around 180 MU in the first year, which is around 70% of RPO for them as a captive power producer for FY 2019-20. The company bought Renewable Energy Certificates (RECs) of around 170 crore in FY 2018-19 to meet its RPO, It was found that it will be feasible for them with 17% IRR if they put up the above proposed solar PV intervention as they will be avoiding cost of RECs and energy charges for the power procured from generators.
